Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the extra firm tofu dry and cut into 1-inch cubes, then peel and dice the sweet potato into similar-sized pieces.
In a large bowl, toss the tofu and sweet potato with olive oil, garlic powder, smoked paprika, sea salt, and black pepper until evenly coated.
Spread the mixture in a single layer on the baking sheet and roast for 25-30 minutes, flipping halfway through, until the potatoes are tender and tofu is golden.
While roasting, place the chopped kale in a bowl with the tamari and nutritional yeast, then massage with your hands for 2 minutes until the leaves are softened and dark green.
Warm the black beans in a small saucepan over low heat until heated through.
Divide the massaged kale between two bowls, then top with the roasted sweet potato, crispy tofu, and black beans.
Sprinkle each bowl with hemp seeds before serving for an extra protein boost.
