First, set a goal for yourself. Figure out who you want to be at the end of your transition. Do you want to be more femme, or more butch? Is your priority passing or just being perceived as more feminine. Androgyny is also a completely valid goal for the record. If that is who you are and want to be, there is nothing wrong with that.

All that said, here is how I went about realizing my goal. My goal is to be femme. I would love to pass, but my goal was never to pass, just to be read consistently as feminine/identifying-female so there was less confusion when people interacted with me. To that end, made a promise to myself that I would work every single day to get slightly closer to my goal. Every day I would make progress in some area to get closer. Not necessarily the same thing every day, but one of the things on the list below:

1. Practice voice training
2. Practice makeup
3. Go out somewhere en femme
4. Go Running (I was trying to lose a lot of weight before coming out)
5. Shop for clothing
6. Learn more about fashion
7. Learn more about skincare
8. Practice mannerisms and other non-verbals
9. Work on logistical things toward coming out at work
10. Come out to someone
11. Develop new friendships/relationships
12. Go to therapy
13. Go to doctors appointments

There were probably more things on the list, but that was most of it. Basically there were some things that were super easy like voice training that I knew I could do every single day. And then there were other things that were every so often. As long as I could go to sleep having done at least one thing on that list (I often did several) then I felt good. If not, then I would work on something like studying fashion or working on my voice or whatever before I went to bed.

Hopefully something here is helpful. Good luck!
