Make the sauce:

1. In a small bowl, mix the chipotle peppers, lime juice, and vegan mayo until smooth.
2. Taste and adjust for spice and acidity. Chill until ready to use.

Set up the breading station:

1. In a medium-sized bowl, whisk the aquafaba with the tapioca flour until fully combined.
2. In a second shallow bowl or plate, add the all-purpose flour.
3. In a third shallow bowl, combine the panko breadcrumbs, garlic powder, onion powder, salt, and pepper.

Bread the mushrooms:

1. Line a baking sheet with a wire cooling rack.
2. Working in small batches, dip the oyster mushrooms into the aquafaba mixture, then dredge in flour, then return to the aquafaba, and finally press firmly into the panko mixture to fully coat.
3. Transfer to the wire rack. Repeat until all mushrooms are breaded.

For deep frying:

1. Heat several inches of oil in a medium cast iron or heavy-bottomed pot over medium-high heat.
2. After about 7 minutes, test the oil by dipping a chopstick in—if bubbles form around it immediately, the oil is ready (350 to 375°F).
3. Fry the mushrooms in small batches, avoiding overcrowding. Cook until golden brown and crispy, about 2 to 3 minutes.
4. Transfer to a clean wire rack to drain while you finish the remaining batches.

For air frying:

1. Preheat your air fryer to 400°F.
2. Spray the breaded mushrooms on both sides with cooking spray.
3. Air fry in a single layer (you may need to do this in two batches). Air fry for 4 to 6 minutes, flip, then cook for 4 to 5 minutes, or until golden and crispy.

To serve:

1. Preheat a dry cast iron skillet over medium to medium-high heat.
2. Warm the corn tortillas for 20-30 seconds per side.
3. Wrap in a clean towel or foil to keep warm while you prep the rest.
4. Fill each tortilla with the cabbage, crispy mushrooms, cilantro, and a generous drizzle of the chipotle-lime sauce.
