Chris Coleman's side will face the Irish at the Cardiff City Stadium next Wednesday.
Bale will form past of Wales' plans amid intense speculation regarding his future at club level.
The Spurs talisman continues to be heavily linked with a record-breaking switch to Real Madrid and has sat out a number of recent fixtures as he looks to overcome a knock.
Coleman has, however, included Bale in a 23-man squad alongside the likes of Wolves goalkeeper Wayne Hennessey and Cardiff City striker Craig Bellamy.
Hennessey missed the majority of last season after suffering two cruciate ligament injuries, while Bellamy is readying himself for the start of a Premier League campaign with the Bluebirds.
Another man preparing for life in the top tier of English football, Crystal Palace's teenage midfielder Jonathan Williams, is also included, while Swansea City defender Ashley Williams will once again skipper the side.
