Tips for vegan nutrition while weight lifting?

A lot of guides online suggest some hard to get or not widely available foods (idk where to find tempeh and quinoa is a bit expensive, for example). But I'm kinda doing the math in my head and having a hard time meeting protein intake goals (probably about 150g per day at least). I did get a protein supplement and it will help I guess, but im not great at meal planning. For anyone who lifts and is vegan, what do you do?
