The veteran fly-half has been an inspirational figure in Glasgow's climb to the top of the Magners League standings in what has been a superb season so far.
Parks has featured in all 10 of the Warriors' Magners League fixtures this term and became the first player in Magners League history to score 1,000 points in the competition.
That form has seen him earn a recall to the national side following a 14-month absence, with his last cap coming during the 2008 autumn internationals.
"I'm just looking forward to bringing my Glasgow form to Scotland," said Parks, after he replaced Edinburgh's Phil Godman in the No10 shirt for Saturday's trip to the Millennium Stadium.
"I certainly feel as if I'm playing well and I'm really enjoying my rugby.
"It's been great this year - the guys are on top of the competition, which makes it really worthwhile.
"I've enjoyed the season and I'm looking forward to be back playing for Scotland. It's been a while since I had my last cap."
Parks comes into the Scotland side on the back of a disappointing 18-9 defeat to France at Murrayfield last weekend and the 31-year-old admits that improvements must be made if they are to make amends against the Welsh.
Andy Robinson's men haven't scored a try in their last three internationals and, despite being best known for his prowess with the boot, Parks hopes he can guide his side to greater attacking success.
"I like to think I can bring certain things into a game and obviously Andy's picked me for certain reasons," added Park
"The boys are quite disappointed with the result at the weekend so really looking forward to stepping up and challenging Wales this week.
"It wasn't a great start and I think the guys know that. There were some good parts and obviously some bad parts.
"I'm hoping that we can correct the things we did wrong, but the biggest thing is we need to score tries."
