Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu for 15 minutes to remove excess moisture, then slice the block into long, thin strips.
In a medium bowl, toss the tofu strips with tamari, garlic powder, and nutritional yeast until every piece is evenly coated.
Arrange the tofu on the prepared baking sheet and bake for 25 minutes, flipping halfway through, until the edges are golden and crispy.
While the tofu bakes, whisk together the peanut butter powder, water, and sriracha in a small bowl to create a smooth dipping sauce.
Fill a shallow dish with warm water and dip one rice paper sheet for about 5 seconds until it becomes pliable.
Lay the wet rice paper flat on a clean surface and place a few strips of baked tofu, carrots, cabbage, and cilantro in the center.
Fold the bottom of the rice paper over the filling, tuck in the sides, and roll it up tightly to seal.
Repeat the process with the remaining rice paper sheets and serve the rolls immediately with the spicy peanut dipping sauce.
