Let the ribeye sit at room temperature for about 45 minutes. Lightly coat it with cooking oil and season generously with kosher salt.
Preheat the smoker to 250°F. Add a few chunks of hickory wood.
Place the steak on the smoker and cook until it reaches an internal temperature of 115°F.
Remove the steak and place it on a wire rack. Prepare the grill for direct searing over hot coals.
Add the shrimp to a bowl with the smoked paprika, chili powder, garlic powder, salt, black pepper, and cooking oil. Toss until evenly coated.
Heat the grill to about 500–600°F. Place the steak directly over the hot coals and sear for 60–90 seconds per side.
Transfer the steak back to the wire rack and let it rest for 8–10 minutes.
Place a cast-iron skillet over the hot coals and heat it for 5–6 minutes.
Add the soy sauce, honey, rice wine vinegar, sesame oil, sweet chili sauce, red pepper flakes, minced garlic, and butter to the skillet. Stir to combine.
Add the shrimp and cook for 60–90 seconds. Flip and cook for another 60–90 seconds, tossing them in the honey garlic sauce before removing from the heat.
Slice the rested ribeye and serve with the honey garlic shrimp.
