Well, I first Googled "paragliding lesson Tenerife" and this yielded a full page of links. When I checked them out, the one that would have been perfect for you (www.airborne.uk.com) came with accommodation included too, something I'm not sure you're also after.
You could try Googling the Spanish version of the enquiry: parapente tenerife and, if your browser has a built in translator, you could examine these options.
