HoG, Aegis, go from there really. If you need damage you get say a wits end, since it's not tooo expensive (triforce would be optimal, but it would set you really far back because you're jungling and will have less gold), if you need tank, get whatever tank item you need. Randuins is good on him since you can easily get into their team. Sunfire cape is also good, though I don't see it much on jungle shen.
