Launch a game and hit Tab on your keyboard. Then map under the options for "Input (this machine)". Using Pole Position as an example you will bind your joystick under the "Dial Analog Inc" for turning right and "Dial Analog Dec" for turning left. Gas, brake, and shift are mapped to "Pedal 1 Analog Inc", "Pedal 2 Analog Inc", and "Gear Change" options.
