In addition to the vegan food pyramid, there are a few aspects you should keep in mind. No vegan foods are a relevant source of vitamin B12 unless they are enriched with it, so you will have to take a supplement. Selenium may be a problem, too, at least in Europe; plants here contain very little selenium. Brazil nuts are sometimes recommended as some sort of "supplement". however their selenium content may vary a lot, and in addition, they may accumulate radioactivity; thus, it may be safer to take an ordinary supplement. Either way do not consume more than 2 per day. Pregnant women, children and teenagers should not eat any at all.
There are very few vegan foods that contain vitamin D. In the summer, spending a lot of time outside may be enough; in the winter, you definitely need to take a supplement.
Similarly, you definitely need an additional source of iodine. Used iodised salt andtake a supplement or eat algae with known content of iodine (otherwise it might easily get too much).
