Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut it into 1-inch cubes.
Place the tofu cubes, chickpeas, broccoli florets, and diced sweet potato onto the prepared baking sheet.
Sprinkle the garlic powder, smoked paprika, sea salt, and black pepper over the tofu and vegetables, tossing well to coat evenly.
Roast in the oven for 25-30 minutes, flipping halfway through, until the tofu is golden and the vegetables are tender.
In a small bowl, whisk together the tahini, lemon juice, and nutritional yeast, adding a teaspoon of water at a time until a creamy consistency is reached.
Assemble the bowl by placing the cooked quinoa at the base and topping it with the roasted tofu and vegetable mixture.
Drizzle the creamy tahini dressing over the top and garnish with the hemp seeds for added texture and protein.
