1. Pre-WeePee: As I mentioned in a previous post, I take DS to the toilet after he eats, so that there is a pattern to his WeePee association.
2. En Route to Toilet: I carry him in one arm, facing away from me. I use the other arm to unsnap his onesie. I found that holding him upright while unsnapping puts enough tension on the snaps that I can pull them apart by just pulling one side. If he's wearing trousers that day, I take these off before walking to the toilet.
3. Parent Placement: Upon arriving at the toilet I either sit on an exercise ball, a stool, or I kneel/squat.
a) Exercise Ball: I have an exercise ball in one bathroom that I use for me to sit on while holding DS on the toilet. I found this to be the easiest "seat" for me because I can sit while I undo DS's diaper, then roll forward to adjust DS's placement on the toilet. Once I'm done, I'm able to easily stand and then I can just kick the ball under the sink and out of the way until next WeePee.
b) Stool: Similar to ball, but stool height can vary - I have a shorty that can help if DS is taking a long time to decide if he actually wants to go.
c) Kneel/Squat: In the bathroom without the ball, I usually kneel on one leg (think marriage proposal or youth soccer photo), put DS on the thigh of the bent leg while I undo his diaper, then lift onto the toilet as before. This is slightly harder, but I consider it part of my overall abdominal workout/core strengthening routine. Sometimes I will move from a kneel to a squat and DS provides enough counterweight that I don't tip over backward. Usually.

4. Unfastening The Diaper: If I am using diapers that have velcro or sticky tabs, I re-secure these tabs to the back side of diaper before I remove it from the baby. This facilitates easier diaper replacement once baby is done WeePeeing. If the diaper is still clean, I will tear off a little bit of TP for post-WeePee clean up so that I can continue with the same diaper. If I'm using cloth diapers and it's soiled, I usually dump the diaper into the wet bin after I've used it for any necessary wiping.
5. Removal of Diaper: I try to lift DS out of the diaper in a way that keeps the diaper open on my lap so that I can just sit him back into it when he's done. But usually the diaper falls to the ground or sticks to his legs or clothes so I have to kind of wiggle him about until the diaper is completely off. (This part of my technique is lacking.)
6. Position of Baby on Toilet: I hoist DS with one hand under each of his armpits and lift him toward the toilet back-first. I keep him only high enough that his bum will clear the seat, that way his legs catch on the toilet seat edge and ideally don't go into the basin (although they have). This can be a strenuous hold depending on your shoulder strength and the weight of the baby. I frequently put my elbows on the edge of the toilet seat for support. Since I don't have other children or a spouse who pee on the seat, I'm okay doing this in terms of cleanliness, but should you be faced with a less-than-desirable toilet situation, this would need to be adapted. I have found that paper seat covers work well in public toilets, and I have thought about ordering a pack to take with me in case the facilities don't have any.
7. Going: Once baby is placed over the toilet, make a "pss-pss" or "sss-sss" or some noise of your choice that you want to mean "It's OK to go pee and/or poop now, Baby." If all goes well, your child will decide to "go" and you will be filled with an undeserved sense of accomplishment and pride. (Don't cling to the feeling too long. Before you know it, baby will take a clandestine poop while you aren't paying attention.) My DS usually takes a few seconds to look around the bathroom before he kind of zones out and then "goes." If he doesn't zone out, he's likely not going.
8. Not Going: My DS arches his back and tries to get his feet on the toilet seat to stand up when he doesn't need/want to go, so it's pretty simple for me to tell if we are going to WeePee or not. I'm sure your baby will have his/her own way to say "Not now."
9. Reinforcement: If the baby goes, I usually say, "Good Job" or something like it in my best high-pitched Mommy Voice. He usually smiles, which may be because he's associated his actions with the reward of my praise or it may just be that he's happy to be rid of his latest bodily waste. Hard to tell.
10. Wrapping Up: When DS is done, I lift him to standing on the front lip of the toilet seat and hold him with one arm while I use the toilet paper I'd previously torn off to give him a cursory cleaning - enough to prevent dripping while I take him from the toilet to the changing table. I then put the diaper back underneath him (unfastened) and stand up, flush, and take DS to the changing table, where I either properly replace his diaper, or put on a new one, depending on the damage.
