Track last known location of iPad mini (2) without "Find My Phone"
If you have not set up any tracking service, then you will not be able to track the device. The device does not save its location history to the cloud without such a service being set up.

If your iPad had a SIM card, you can able to talk to the provider who may be able to tell you where the device is — not as accurate as GPS but will give you an idea of the country at the very least.

You're not going to be able to 'block' the iPad either since you haven't activated Find my iPhone, but the SIM card provider can block the SIM card.
