Preheat oven to 425°.
Combine the first 7 ingredients in a small bowl.
Trim fat from roast. Brush roast with soy sauce, and rub with pepper mixture. Place roast on a broiler pan coated with cooking spray. Insert meat thermometer into thickest portion of roast. Bake at 425° for 10 minutes. Reduce oven temperature to 350° (do not remove roast from oven), and bake an additional hour or until the thermometer registers 145° (medium-rare) to 160° (medium).
Place roast on a serving platter, and cover with foil. Let stand 10 minutes before slicing.
