Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Press the extra firm tofu to remove excess moisture, then cut it and the sweet potato into 1/2-inch cubes.
In a large bowl, toss the tofu and sweet potato cubes with the olive oil, garlic powder, smoked paprika, sea salt, and black pepper until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25-30 minutes, flipping halfway through, until the potatoes are tender and the tofu is golden.
While roasting, place the chopped kale in a bowl with the lime juice and a pinch of salt, massaging with your hands for 1-2 minutes until the leaves soften and turn dark green.
Warm the black beans in a small saucepan or microwave until heated through.
Assemble the bowl by layering the massaged kale at the bottom, then topping with the roasted sweet potato, crispy tofu, and black beans.
Finish the bowl by sprinkling the nutritional yeast and hemp seeds over the top for a boost of savory flavor and plant-based protein.
