Preheat your oven to 400°F (200°C) and lightly line a baking sheet with parchment paper.
Press the tofu with a clean towel to remove excess moisture, then cut it into bite-sized cubes.
In a bowl, gently toss the tofu cubes with garlic powder, smoked paprika, salt, and pepper, and a drizzle of olive oil.
Spread the seasoned tofu evenly on the baking sheet and bake for 25-30 minutes, flipping halfway through, until crispy and golden.
While the tofu bakes, prepare the quinoa according to package instructions if not already cooked and rinse the chickpeas.
Chop the red bell pepper, cucumber, and if desired, any additional veggies of your choice. Place these along with the spinach in a large bowl.
Add the cooked quinoa and chickpeas to the vegetables.
Once the tofu is done, allow it to cool slightly then add it to the bowl.
In a small bowl, whisk together lemon juice, a dash of olive oil, salt, and pepper to create a light dressing.
Drizzle the dressing over the power bowl, toss gently to combine all ingredients, and serve immediately.
