Preheat the oven to 400 degrees.
Gently mix the crab cake ingredients: the crabmeat, shallot, garlic, ginger, honey, egg white, coconut milk, lime juice and zest, panko, cilantro, sriracha, if using, and pinches of salt and pepper.
Form into patties, and coat with extra panko on all sides.
Place on a baking sheet lined with parchment paper and bake for 10-15 minutes or until golden brown.
I turned on the broiler for the last 1-2 minutes. You can flip halfway through, but I forgot to, and it worked out just fine.
Alternatively, pan fry the cakes in a skillet.
Make the sauce: To a food processor, add the tofu, avocado, lemon juice, garlic, wasabi, onion powder, if using, and pinches of salt and pepper.
Process until smooth, and chill until serving.
