The Robins hold a 2-0 advantage from Sunday's first leg at Whaddon Road as they prepare to meet the Gulls for the fifth time this season.
But Town's preparations remains exactly the same for the crunch clash, with the players enjoying a swimming session on Tuesday, some ball work on Wednesday before travelling down to Plainmoor on the day of the game.
"It's a different concept, two-legged semi-final, we've got a two-goal advantage to start with. We've got to make sure that doesn't affect our mindset," Yates said.
"It's just another game, it's just a game where we've got a slight advantage before we start, we've got to do everything we can to make sure that stays the same come 10 o'clock on Thursday night.
"Nothing changes, our preparation won't change, the boys have got a pool session but we've done that throughout the season with midweek games. Travelling, everything's the same. We want another performance where we go out and enjoy it, if we enjoy it then we've got a great chance of progressing."
