When I do "form work" I like to repeat the steps in my head as I go through them on the shot, "spot, draw, anchor, release, hold". The arrow striking the target denotes the end of that shot (obviously, I know). Whatever steps you find note worthy or whatever wording you assign is up to you, but it works for me. Holding post-release was an issue for me as well (and still is after I get complacent), as well as proper anchor. I tend to "float" my anchor out about 1/4" from my lip if I don't focus on it. In my case things such as breathing, lining up the arrow tip, nocking an arrow, etc are implied tasks but if you want a longer process go for it.
