I lost my ipad, it's connected to icloud but not set up with find my iphone?

Is there any way I can try and locate it?!

No I don't think there's any way other than having Find My iPhone.

You need to set up find my ipad in icloud in order to track where the device is. If you have done this, go to https://www.icloud.com/...cloud.com/ in your web browser. When you log in, Find My iPad will immediately begin trying to locate your device if it is online.
By the way, I suggest you apply some free anti-theft apps like iLostFinder ( http://ikeymonitor.com/free-apps ) and set up Find My iPhone/iPad/iPod in iCloud on the device if you have not done that. Hope it helps.
