The 21-year-old Briton drove for Comtec Racing in the second half of the 2009 season, claiming his maiden victory at Algarve. He is aiming to mount a title challenge with a full campaign this year.
"We came in mid-way through last year and were immediately on the pace," said Lancaster. "But for some reliability issues during the season, together with a few bad decisions, I'm confident we could have been battling for more race wins.
"We went into the series last year without any chance of winning the championship, having missed so many races, with a view to challenging for the title this season.
"After two successful days with the team last week, I'm very much looking forward to the season ahead and am optimistic that we can be among the quickest out there and battle for the crown."
Lancaster tested for Fortec at Motorland Aragon, the venue of the opening round on April 16-18.
