In a medium saucepan over medium–high heat on the stove, warm the oil. Add the onion and garlic and cook until soft, about 5 minutes, stirring occasionally. Add the remaining sauce ingredients. Bring the mixture to a boil, then reduce the heat to a simmer and cook until reduced to 120 millilitres about 10 minutes, stirring occasionally. Remove from the heat and allow to cool. Purée the sauce in a food processor or blender with the lid ajar. Cover and refrigerate until ready to use. Bring to room temperature before serving.

In a small bowl mix the rub ingredients. Press the mixture into the surface of the roast, cover with plastic wrap and refrigerate for 3 hours or as long as 24 hours. Allow the roast to stand at room temperature for 15 to 30 minutes before grilling.
Soak the wood chips in water for at least 30 minutes.
Prepare the grill for indirect cooking over medium heat (180°C to 230°C).
Brush the cooking grates clean. Drain and add the wood chips to the charcoal or to the smoker box of a gas grill, following the manufacturer’s instructions. When the wood begins to smoke, sear the roast over direct heat, with the lid closed, until both sides are nicely browned, about 5 minutes, turning once. Slide the roast over indirect medium heat, close the lid, and continue cooking to your desired doneness, 20 to 30 minutes for medium rare. Remove from the grill and let rest for 3 to 5 minutes. Cut the roast against the grain into thin slices.
