Mix: Add all ingredients (except oil) to a food processor. Pulse a few times, scraping down the sides as needed, just until blended (there should still be some bigger chunks for texture).
Shape: Form dough into 9 or 10 balls, then flatten slightly into thick patties.
Refrigerate (optional): At this point, you can cover the patties with plastic wrap and let them chill in the fridge to firm up. This makes handling them during cooking easier, especially if you're cooking them on the stove.
Oil: Brush each patty all over with oil.
Cook*: Preheat air fryer to 400°F (204°C). Add vegan crab cakes and cook for 10 to 15 minutes, until firm and golden brown. You may need to flip them over during cooking if you notice them cooking unevenly (depending on your air fryer).
Serve warm with vegan tartar sauce and lemon slices!
