Prep the Soy Curls: Start by soaking the soy curls in warm water for about 10 minutes. They'll puff up and soften. Once rehydrated, drain them.
Make the Marinade: While the soy curls soak, whisk tamari, apple cider vinegar, maple syrup, sriracha, oil, liquid smoke, paprika, garlic powder, and black pepper in a bowl. Add the soy curls, ensuring they're fully coated in this flavorful marinade. Let them marinate for about 10 minutes.
Cook: Heat a skillet over medium heat. Add the marinated soy curls, spreading them out for even cooking. Fry until crispy and browned, stirring occasionally, about 7-10 minutes until the marinade has been absorbed and evaporated. Deglaze the pan with water if necessary.
Alternative Cooking Method: Preheat your oven or air fryer to 350°F (175°C). Spread the marinated soy curls in a single layer on a baking sheet lined with parchment paper or the oven or spread them evenly in the air fryer basket. Bake for 15-20 minutes in the oven, stirring halfway through, until they are crispy and browned to your liking. Bake for 4 - 5 minutes in the preheated air fryer. Watch them closely towards the end to prevent burning.
Assemble the Sandwich: Toast the bread if you like. Spread a generous layer of vegan mayonnaise on both bread slices. On one slice, layer your tomato, avocado, and crispy soy curl bacon, followed by crisp greens and optional sprouts. Top with the second slice of bread, press down gently, and voilà! Your Vegan BLT is ready to eat.
