Thankfully Care2 has put together a list of vegan sources of essential nutrients, because I don't know when I will ever manage. I will however try to at some point post a detailed list of nutrients and veggie sources, with the per 100g content listed and compared to meat sources - quite useful and enlightening.

The most significant supply of Vitamin D comes from sunlight exposure on the skin. Vitamin D-2 supplements are available, as well as Vitamin D fortified plant milks & cereals. Fortified vegan products contain Vitamin D-2 (ergocalciferol) as opposed to animal-derived Vitamin D-3 (cholecalciferol).

Vitamin B12
Red Star ‘Vegetarian Support Formula’ Nutritional Yeast, B-12 fortified non-dairy milks and cereals. Vegan B-12 supplements: VegLife (certified vegan) B-12 supplement, Twin Labs ‘Vegetarian Formula’ B-12 Sublingual Dots, etc. [Note that B12 is not readily available from vegetable sources. While some think this indicates that humans are "meant" to be omnivores, it has more to do with washing our vegetables and better food hygiene - B12 is naturally found in dirt and bacteria. Importantly, don't believe the hype about natural food sources. Just supplement kay?]
