(Optional) Combine the marinade ingredients in a quart-sized container.
Cut the block of tofu lengthwise into four thin slices. Break each slice into bite-sized pieces and place them in the marinade.
(Optional) Allow the tofu to marinate for about 3-12 hours.
Set up three shallow bowls with the starch mixture, non-dairy milk, and breadcrumb mixture. Dip each side of each tofu piece into the starch, milk, and breadcrumbs until they are well-coated. Place the tofu pieces into the basket of the air fryer in a single layer.
Spray the tofu generously with oil. Cook them at 400° F (204° C) for about 10-15 minutes. Pause the air fryer roughly halfway through cooking to flip the tofu and spray the other side.
When the nuggets appear golden brown, use a heat-safe turner to remove the nuggets and serve.
Store leftovers in the fridge for 3-4 days or freezer for up to 2 months. Reheat them in the air fryer at 325° F for about 5 minutes or until heated through.
