Learn to kite-board or windsurf in Pattaya, or rent equipment by the hour or by the day. There are 2 well established windsurfing and kite-boarding centers in Pattaya, and they are both located on Na Jomtien Beach. They all offer professional training packages and equipment hire, I couldn’t offer you an opinion on which is best, but they each have their own website, so I suggest you start there.
The 2 Pattaya windsurfing and kite-board centers are located within walking distance of each other on Na Jomtien Beach. There are live links to each of their websites, and a Google map at the bottom of the page.
