Preheat smoker or grill on low heat and add wood chips according to manufacturer's instructions.
Toss shrimp with olive oil, salt and pepper.
Lay shrimp on smoker rack in a single layer and close the lid. Check shrimp after 10 minutes and keep a close eye on them. Smoke shrimp until just cooked through, about 15-20 minutes total.
While shrimp are smoking, stir together ghee or butter, garlic, herbs and salt to taste in a small bowl. Drizzle over cooked shrimp and toss to coat. Serve remaining garlic herb butter mixture as a dipping sauce.
Notes
For dairy-free: substitute olive oil for ghee in sauce
