Preheat your oven to 400°F (200°C) 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 the sweet potato and dice into 1/2-inch cubes to ensure even roasting.
Rinse and drain the chickpeas, then pat them thoroughly dry with a clean kitchen towel to help them crisp up.
In a large mixing bowl, toss the tofu, sweet potato, and chickpeas with avocado oil, garlic powder, smoked paprika, sea salt, and black pepper.
Spread the seasoned mixture in a single layer on the prepared baking sheet and roast for 25-30 minutes, flipping halfway through, until the sweet potatoes are tender and the tofu is golden brown.
While the vegetables roast, place the baby kale in a large serving bowl and massage it with the lemon juice for 1 minute until it softens and turns bright green.
Once roasted, remove the tray from the oven and arrange the tofu, sweet potato, and chickpea mixture over the bed of kale.
Garnish the bowl with nutritional yeast and hemp seeds before serving warm.
