The 20-year-old joined Linfield on a one-year deal in the summer after being released by Everton, and has made an immediate impact with four goals in nine games, including a memorable brace against Qarabag in the Europa League qualifiers.
His form – coupled with an injury for Paul Smyth – has earned him a return to Michael O'Neill's Northern Ireland squad for the upcoming games against Luxembourg and Germany, and left the impression his spell in the Irish League could be a short one.
"I'm not really thinking about it at all," said Lavery, who earned his only cap to date against Panama last year.
"I'm not thinking about January or next summer, I'm just taking it game-by-game.
"I don't see it as a step back at all. It's just good to be back playing football again and showing people what I can do."
Lavery signed for Everton as a 16-year-old but never made a senior appearance.
"I just remember being completely wrecked after the game, I couldn't really stand," he said.
"But it was nice to get two goals, especially it being the play-offs and the (standard) of opposition against us."
Defender Michael Smith and winger Jordan Jones are out of O'Neill's squad through injury, the manager has confirmed.
Smith has a hamstring injury which ruled him out of Hearts' 2-2 draw with Hamilton on Saturday, while Rangers' Jones left Ibrox on crutches after Sunday's 2-0 Old Firm derby loss to Celtic.
