Dude,
He's not vegan. He said he was vegetarian. There's a big difference.
Trust me. I've been ovo-lacto vegetarian for +10 years. You can get plenty of calories. Getting the right calories is the hard part. Whey protein powders and flax oils are going to help in that department.
If you don't think vegetarians can get ripped, check out this thread:

and I doubt OP event wants to get that toned.
