Narrative:
Training on local. South flow VFR conditions. Aircraft X checked on 20 south to land; I told him to enter a left downwind for runway xx. He never entered the downwind. He flew straight for the airport. Aircraft Y called ready to depart and I cleared him for takeoff runway xx heading 230. I thought it would take him far enough west to not be a factor. As he got airborne; I called traffic then turned aircraft X eastbound. Aircraft Y had to turn to a 250 to avoid the conflict. They passed and aircraft Y got switched to departure. [I] should have turned aircraft Y to a 270 or held him on the ground.
