The goalkeeper spent four years at St James Park before signing for Town on a free transfer in 2014.
Krysiak is looking forward to seeing some familiar faces on Monday but insists his sole focus will be on Yeovil come kick-off.
He told YTFC’s official YouTube channel: “I know a lot of people there who were key in my time at Exeter and made me a more mature player.
“But I’m playing for Yeovil right now and as soon as I go out for the warm up, that’s it.
“I’ll be focused on Yeovil and getting ready for the game.”
Exeter are unbeaten in their last four league matches and currently sit 15th in Sky Bet League Two.
The Grecians have scored the same amount of goals as Town so far this season and Krysiak is expecting to face a forward-thinking Exeter side.
“They have really good attacking players,” he said.
“They’re a possession based team so they’ll try and play it round us but we’re one of the best pressing teams in the league.
“|t will be massive for us to try and steal the ball and score some goals.”
