I went from eating meat maybe twice a week to being almost vegan a few months ago. A few weeks back, I posted something similar.
A friend who has been with me for a loooong time on this weight loss journey pointed out that back when I was in active weight loss, I often mentioned that protein made a big difference. I thought I was being pretty careful--but I tried tracking a few days and saw that I was a LOT lower than I had thought in protein percentages. I'm still a lot lower than I used to be, but I think I'm finding a better balance. (I was trying to avoid adding too much soy, but I think it did make a difference when started adding a little more.)
I also brought up the energy levels with my mother and sisters just to see if any of them had issues I didn't know of (thyroid, anemia, whatever) and my mentioned that even though she eats meat, she feels better when she takes a B12 supplement. I had actually picked up a B complex, but was a bit worried since I was in a hurry and didn't check carefully--turns out it's really high doses. But hearing that she needed the supplement even with meat helped me relax a bit--and I really did start feeling better.
Anyway, sounds like you have vitamins and minerals covered--but you might want to take a look at protein percentages.
The friend who mentioned the protein actually does coaching for transitioning to veg*nism. I decided to set up a session, since I don't want this to fail just because I'm missing something obvious.
