Have said this before, will say it again in case it helps. I don't know why this works for me but it manifestly does.
1. Write slides, more than you think you need, and try to have fewer than 1/4 of them include bullets.
2. Print the slides out, one sheet per slide.
3. Tape slides to wall in a grid.
4. Rehearse the talk to the grid of slides on the wall with a sharpie in your hand. Any time you have trouble with a slide or trouble transitioning from one slide to the next, note it (or fix the slide) on the paper slide.
5. Reorganize slides in Keynote (or whatever), print them out again, repeat.
This may just be a bit of a ritual for me, but one thing it definitely does is it creates a context where I don't feel silly rehearsing by myself.
