Defender Neil Taylor is not included after being
ruled out for four to six weeks
after suffering severe bruising on his thigh during Swansea's Europa League win over Petrolul Ploiesti last week.
There is no place in the squad for West Ham defender James Collins and Sunderland midfielder David Vaughan but Brighton's Andrew Crofts and Birmingham City full-back Neal Eardley are recalled.
Manager Chris Coleman has included Bale in his squad as speculation over a proposed world-record transfer from Tottenham to Real Madrid continues to intensify.
The 24-year-old failed to report for training with Tottenham both on Tuesday and Wednesday and manager Andre Villas-Boas said the club will consider fining the player.
"As far as we're concerned, unless we're told he's unavailable then he's very much in our plans," Coleman said.
"Of course we've got the saga of if he's going to move from Tottenham or is he going to stay, we know that's going on and that's not easy for Gareth or Tottenham.
"Sometimes when players have a rest and they've not played a lot of football, maybe they won't last the 90 minutes, but sometimes there's a freshness about them and that rest does them good physically.
"The difference with Gareth is that mentally there's a lot been going on, but if we can have him then of course it's a boost for us.
"It's not been easy for him, there's a lot of pressure on him.
"But he's the type of lad that is very unassuming, he has a calm personality, he's very grounded. I would imagine he wants it concluded like everybody does."
Wales travel to Macedonia for a qualifier on Friday, 6 September before hosting Serbia at Cardiff City Stadium the following Tuesday.
Chris Coleman's side are unlikely to qualify from Group A. They lie 13 points behind leaders Belgium and 10 adrift of second-placed Croatia.
