Place steak directly on smoker and smoke for 20 minutes at 180°F. After 20 minutes, remove from the smoker and put on plate. Tent with aluminum foil.
Place grill grates on smoker and increase temperature to 425°F. Once heated, place steak on grill grates and cook until desired internal temperature, test with thermometer. Always cook to temperature and not time. However, It should take about 4-6 minutes a side for medium.
When steak reaches desired temperature, remove from smoker and allow to rest 10 minutes before slicing.
Slice the steaks AGAINST the grain of the meat in ¼" wide strips so it will be nice and tender. Tilting the knife and slicing at a 45° angle will also make the strips a little wider since this steak is very thin.
Notes
Sear over an open flame to get the best char on the steak
Don't smoke too long, this will make the meat tougher. 20-30 minutes max
