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 into 1/2-inch cubes.
Peel and cube the sweet potato into bite-sized pieces and rinse the canned chickpeas thoroughly.
In a large bowl, toss the tofu, sweet potato, and chickpeas with olive oil, sea salt, black pepper, garlic powder, and smoked paprika until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 minutes, tossing halfway through, until the sweet potatoes are tender and the tofu is golden.
While the vegetables roast, place the chopped kale in a bowl and massage it with the lemon juice for 1-2 minutes until it softens and turns a vibrant dark green.
Assemble the bowl by placing the cooked quinoa and massaged kale at the base.
Top with the roasted sweet potato, chickpea, and tofu mixture.
Garnish with nutritional yeast and hemp seeds, then finish with a creamy drizzle of tahini.
