West Ham have had three bids rejected for the former Rochdale man and have been publicly courting the 24-year-old.
Hogan missed the 5-1 win over Eastleigh in the FA Cup through injury with a buttock injury but has been training since Monday.
“His buttock is fine. He's trained all week and is available for selection,” Smith said.
“Finding out where his head is at is a conversation I'll have with him Friday morning. There's been a lot of speculation and offers coming in for him.
“He's got a value to us and we want to keep him at the football club unless a bid that meets the valuation comes in.
This time last year, Brentford were rocked by James Tarkowski downing tools and refusing to face Burnley but Smith believes Hogan will only be interested in scoring a hat trick.
The head coach added: “He's been no different. He's trained well and enjoyed it. He's scored a few goals in training and he always enjoys it when he does that.
“I would very much doubt it (him doing a Tarkowski). You have to have the chat with him and see whether he thinks it'll affect him for the game. I don't think it will but it's conversation I'll have with him.”
He explained further: He is a driven person and you can see that by his demeanour on the pitch. His goalscoring record since he has come back has been excellent.
“I fully expect him to want the opportunity to score a hat trick against Newcastle and show people who may question his credentials that he can do it.”
