It was only Bale's second Premier League start since signing on loan from Real Madrid last summer.
But the Welshman has denied that he has felt frustrated during his second spell in north London.
"The most important thing is we knew we've not been on a great run and it was important to get back to winning ways," he told BBC Match of the Day.
"It's not just about scoring. It's about our all-round play and helping the team. I'm delighted with the goals and the assist and whatever I can do for the team.
"I've been happy all season. In the dressing room I feel comfortable and I'm having fun. I'm happy and I'm sure it's showing on the pitch.
"I wasn't upset to be substituted. There are a lot of games to come. It's important to keep building minutes each game."
