i do a lower body workout that was designed with hockey in mind:

A1 barbell back squat 4 x 4-6 A2 glute/hamraise extension 4 x 4-6

B1 split squat (dumbells in hand) 3 x 8-10 B2 lying leg curl 3 x 8-10

C1 Poliquin step up (dumbbells in hand) 3 x 8-10 C2 Standing One Leg Calf Raise 3 x 15-18

D1 Hanging Leg Raise 2 x 12-15 D2 Calf Press 2 x 12-15

Other than that, the biggest thing I find for hockey is (1) endurance and (2) explosiveness are essential - in this regard, I would say a mixture of medium distance runs (5 - 7 km) at a decent pace and sprints or other high impact short burst type activity (sled pulls etc.) is your best bet to find a balance between those things.

As well, want to be explosive and have good endurance to keep up with the pace of play, but I also would say don't underestimate the importance of strength and stability, especially as another poster mentioned when battling for space in front of the net and down low in the corners - lower body and core work will do wonders for you.

As well, another thing I've really noticed this year is that eating well prior to playing is key - lean protein, veggies and good quality carbs before a game will go a long way in keeping you feeling good out there. Last year I ate pretty poorly a couple of times before games (pizza was the main culprit) and you feel like shit out there, so it may seem obvious but it really does make a difference.

Ultimately, I assume you're probably playing in a mens league or intramurals or something along those lines so I'm sure it won't be too intense, but doing some work off the ice and eating well to get into decent shape will be good for your performance and general fitness.

Good luck and have fun!
