Place the diced sweet potatoes on a large baking sheet.
Drizzle the sweet potatoes with 2 teaspoons olive oil. Sprinkle with sweet potatoes with ½ teaspoon chili powder, ½ teaspoon garlic powder, ½ teaspoon cumin, smoked paprika, ¼ teaspoon salt, and black pepper.
Toss the sweet potatoes until evenly coated. Spread the sweet potatoes in a single layer.
Bake the sweet potatoes for 22 to 25 minutes, or until tender and lightly browned.
While the sweet potatoes bake, pat the chicken dry with paper towels.
Sprinkle the chicken with the remaining 1 teaspoon chili powder, remaining ½ teaspoon garlic powder, remaining ½ teaspoon cumin, onion powder, and remaining ¼ teaspoon salt.
In a large skillet over medium heat, add the remaining 1 teaspoon olive oil and the chicken. Cook 6 to 7 minutes per side, or until the internal temperature reaches 165 degrees F.
Transfer the chicken to a cutting board. Let the chicken rest for 5 minutes.
Dice or slice the chicken.
In a small bowl, add the Greek yogurt, salsa, lime juice, water, chili powder, garlic powder, cumin, and salt. Using a wire whisk, mix until smooth.
Divide the romaine lettuce between 4 bowls. Top each bowl with roasted sweet potatoes, chicken, black beans, corn, cherry tomatoes, red bell pepper, red onion, shredded cheese, and cilantro.
Drizzle each bowl with the creamy Tex-Mex yogurt sauce. Serve with lime wedges.
