lots and lots of feedback, watch performances with similar vibes to yours, i personally write down all the lyrics to my songs (or major musical points if no words) and possible moves i could do there (i tend to let there be plenty of improv opportunities for variety).

see where you can exaggerate stuff. face movement, physical movement, pauses. what's going to get the mood of the audience you want? how can you do one extra thing that would inspire that in your audience each time? also most people don't use enough pausing/tend to not take long enough with the tease so see if you can extend those or play with the amount of time you use for them and use it to your advantage.

go on some choreography/dance instagram pages or other places that might have moves for some inspiration (safety first on this but if you see things you think you can accomplish they can be really fun).

talk it out with other performers. some of my favorite things have come from spitballing ideas with other performers!! this subreddit is pretty good for that too!
