I really, really wouldn't worry that much about protein as a vegan. It's extremely overrated. If you look at any amount of research regarding protein consumption among athletes, most are taking too much -- they're basically pissing it back out -- and the stronger they get, the less they need to keep their musculature. It's all marketing. Getting .8 grams per pound of bodyweight of complete protein is enough for me, and not a tough target to hit. I worry slightly more about consuming enough calories to train as hard as an athlete should. I'm not sure how much I'm eating at the moment, but even if I'm hitting about 3,000 calories a day that'll barely be enough for my current training program. Remember, I'm training to fight, not to build muscle for hypertrophy. I don't need my body to focus on protein synthesis all that much -- even during strength training, a lot of effort is going towards improving motor neuron efficiency, rather than aesthetics. A proper amount of micronutrients and carbs for recovery is more important than jumping all over the protein train.
