The Football League has announced the final shortlists ahead of their annual awards ceremony on Sunday.
Players will be honoured from each league and young players will also be recognised at the gala ceremony at The Brewery in London.
The 2013 shortlists are based on votes from the managers in the respective divisions.
Seasiders winger Ince, 21 has scored 18 goals in 36 league appearances this season, while striker Murray is the division's top scorer having bagged 29 in 34 games for the Eagles.
Czech Republic international Vydra has hit the net 20 times for the Hornets during his season-long loan spell from Udinese.
As well as being in contention for the Championship gong, Ince and Vydra make the shortlist again for the Young Player of the Year award - along with Palace forward Wilfried Zaha.
