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.
In a large bowl, toss the tofu cubes, chickpeas, and cubed sweet potato with olive oil, sea salt, black pepper, and smoked paprika.
Spread the mixture in a single layer on the prepared baking sheet and roast for 25 to 30 minutes, flipping halfway through, until the sweet potatoes are tender and the tofu is golden brown.
Remove from the oven and immediately sprinkle the hot tofu and chickpeas with nutritional yeast, tossing to coat thoroughly.
Place the fresh baby spinach in a serving bowl and arrange the roasted vegetable and tofu mixture on top.
Drizzle the bowl with tamari and fresh lemon juice, then garnish with hemp seeds for an extra boost of protein and crunch.
