Preheat the air fryer to 400°F (200°C) for 5 minutes.
In a large bowl, combine the shrimp, red bell pepper, zucchini, yellow squash, and broccoli florets.
Drizzle the olive oil over the shrimp and vegetables.
Sprinkle garlic powder, smoked paprika, salt, black pepper, dried oregano, and dried thyme evenly over the mixture.
Toss everything together until the shrimp and vegetables are well coated with the oil and seasonings.
Place the shrimp and vegetable mixture in the air fryer basket in a single layer. You may need to cook in batches depending on the size of your air fryer.
Cook for 6 minutes, then shake the basket or stir the contents gently.
Continue cooking for an additional 6 minutes or until the shrimp are pink and opaque and the vegetables are tender-crisp.
Remove from the air fryer and transfer to a serving dish.
Drizzle fresh lemon juice over the shrimp and vegetables.
Garnish with chopped fresh parsley before serving.
