Vaughan was Huddersfield's matchwinner at Leeds over the weekend, applying a composed finish to Jack Hunt's through ball in the 86th minute to notch his ninth goal for the club since arriving on a season-long loan deal from Norwich last summer.
When asked if Town were ready to offer Vaughan, 24, a deal to keep him at the club permanently, Robins said: "We've got to see, there's plenty of games to go.
"We've still got a lot of work to do and we need to sit down, but now's not the time to talk about it while there's still games to play and things to do.
"There's a lot of planning and preparation going on behind the scenes obviously, but we will see.
"Certainly he has done his case no harm with the way he's performed (against Leeds) not only with his goal, but the way he's put himself about."
Vaughan arrived at the John Smith's Stadium with doubts over his ability to stay injury-free over the course of a season and although he was sidelined with a thigh problem at the end of last year, he has made 29 appearances for the Terriers this season.
Robins, meanwhile, has no problem with Jermaine Beckford's decision to join up with the Jamaica squad this week for their two World Cup qualifiers against Costa Rica and Panama.
Beckford, on loan from Leicester, made his first appearance in two months as a second-half substitute at Leeds.
The 29-year-old, sidelined for 10 games with a hamstring injury, has yet to make his first appearance for Jamaica with whom he qualifies through family connections.
"He wants to play and there's a break and he hasn't played for a while and he wants to go and play for his country," said Robins.
"The good thing for us is he's back playing. He's looked sharp in training.
"He's worked hard to get back and he's been out a long time. I think it's the first time he's been out for such a lengthy period, so it will be new to him.
"He'll be making up for lost time and he wants to go and play and we'll welcome him back in two weeks."
Robins added: "The introduction of Jermaine (against Leeds) was a big lift. His movement for the second goal gave James Vaughan the space to put the ball away.
"He will go away with Jamaica now for a week and hopefully he will stay fit."
Jamaica are scheduled to play Panama on March 22 in Kingston before travelling to play Costa Rica at the Estadio Nacional de Costa Rica four days later.
