The Scotland striker has made two fleeting substitute appearances since returning to fitness after a year on the sidelines with an Achilles injury.
Brighton, currently outside the play-offs on goal difference, head to Huddersfield on Good Friday before hosting Blackpool on Easter Monday, and Mackail-Smith is desperate to feature at some point.
He said: "We've got the big game on Friday, I would love to be involved in that, but I know I have to be patient as the boys are doing really well, we're getting wins and scoring goals.
"It's been great being back among the squad on a matchday. I know I have just got to bide my time, there are still important games to come and I hope I can play a part in them."
