Preheat the oven to 400°F (200°C).
Pat the chicken thighs dry with paper towels.
In a small bowl, mix olive oil, garlic powder, onion powder, paprika, salt, and pepper.
Rub the spice mixture all over the chicken thighs.
Arrange mixed vegetables on a baking sheet.
Place the chicken thighs on top of the vegetables, skin-side up.
Bake in the preheated oven for 35-40 minutes until the chicken is golden brown.
Check the internal temperature; it should reach 165°F (75°C).
Remove from the oven and let it rest for 5 minutes.
Garnish with fresh herbs before serving.
