The on-loan Czech Republic striker came off the bench to salvage a 1-1 draw against Hull City last weekend.
Vydra enjoyed a fruitful loan spell at Championship side Watford last season, but has barely had a look-in since his temporary switch to Albion from Serie A club Udinese.
The 21-year-old ensured Downing avoided defeat in his first game in charge since Steve Clarke left The Hawthorns and could be rewarded with a start at White Hart Lane.
Downing said: "I'm pleased for Matej Vydra because he's been here a while and people have forgotten him a little bit.
"I'm pleased because he's a good type, a good professional who works hard at his game.
"He's in a good vein of form at the moment. He's come on and scored the goal, made some impact in previous games.
"When someone scores a goal their confidence is high so you've got to consider him for a start at Spurs."
Vydra made a name for himself in England by scoring 22 goals for a Watford side that suffered defeat in the play-off final in May.
