Whey powder is not vegan as it is a by product of the cheese industry. It's the liquid that remains after milk has been curdled and strained. Whey powder is generally suitable for lacto vegetarians though.
If you are looking for a vegan protein there are several options:
Soy protein
Brown Rice Protein
Hemp Protein
Pea protein (my favorite)
and there are others, but these are the easiest to find.
