Get to Hat Yai from the border, then take a cheap flight to Bangkok and then another to Udon Thani from where you can get a bus to Nong Khai and the border with Laos for Vientiane . With the right flight connections you should be able to do it in a day.
Other option is to backtrack to KL and fly direct to Vientiane from there with AirAsia.
