Preheat the oven or the Air fryer for the tofu. Preheat the oven to 400°F (200°C) for the Oven method. Line a baking sheet with parchment paper. For the air fryer method, preheat the air fryer to 375°F (190°C).
Prepare the tofu: Press it for at least 10 minutes to remove excess moisture, then cut it into cubes. Toss the tofu cubes with tamari, nutritional yeast, garlic powder, paprika, and black pepper in a bowl.
Cook the tofu. Oven method: Spread tofu on the prepared baking sheet in a single layer. Bake for 25–30 minutes, flipping halfway, until golden and slightly crispy. Air fryer: Place tofu cubes in the air fryer basket. Air fry for 15–18 minutes, shaking halfway through, until crispy.
Make the dressing: In a blender or food processor, combine white beans, lemon juice, mustard, nutritional yeast, garlic, capers (if using), water, salt, and pepper. Blend until smooth and creamy. Taste and adjust the seasoning or add more water for a thinner consistency.
Assemble the salad: In a large bowl, add chopped romaine. Add the desired amount of dressing and toss until coated. Top with crispy tofu, optional croutons, and a sprinkle of black pepper or extra nutritional yeast. Serve immediately with lemon wedges on the side.
