The 41-year-old will link up with Ireland next month and remain with the squad until the end of the tournament, which runs from March 8 to April 3.
“I’m very excited to be joining the backroom staff of the Ireland team,” Vaas said in a Cricket Ireland press release. “There’s a lot of talent and experience in the squad which I’m confident I can add to.”
Left-armer Vaas took a total of 755 wickets in his 111 Tests and 322 one-day internationals and boasts the best figures by any bowler in limited-overs internationals — 8-19 against Zimbabwe in December 2001.
Since retiring he has worked as a bowling consultant for New Zealand and Sri Lanka, as well as coaching in the Indian Premier League.
“It’s great to have Chaminda with us through the build-up as well as during the T20 World Cup,” said Ireland head coach John Bracewell.
“His ability to get wickets in all forms of the game, especially on the sub-continent, was extraordinary. This experience will be invaluable to our bowling group.”
