Hey :) This is my first guide on this site. I have only recently started to play LoL more seriously now and quite enjoy jungling. My favourite champion is of course Gangplank.
Thought I would post this up and see how it goes.

I take smite as you are jungling
Then the second is more up to preference, I like flash as if needed I can quickly run if someone enters my jungle. Also can be used for quick ganks if wanted.

Others may be Exhaust for slowing with a gank but parrley slows anyway.
Ghost for chasing and running but you have raise morale.
Ignite is best out of other choices imo since when you gank but cant cant finish ignite cleans up nicely.

My route is not the best nor will it be. I am not going to lie I am inexperienced but this is the one I use.
I start off at the wolves camp, then move to wraiths camp(smite the blue one) and next is small golums(use health pot before fighting). After these 3 camps go back as you now should have enough for a Vamp Scepter. Once bought head straight out to blue(use raise morale after first attack then usual combo of attack and parrley, once low on hp use smite). Next up is wolves, then wraiths and now Red(same concept as blue) and small golums. Now can either go back or my preference GANK.

Gangplanks ganks usually require you to be communicating with teamates. Let them know when you have your ulti and stuff. Now for ganking let them know who to go for and when(if they play aggressive obviously let them push up for more time to attack them.

Thanks for reading my guide :)
