Piezo-discs come in a wide size range c.a. 7 mm up to around 55 mm. Size/thickness affects the resonant frequency- check out digikey.comDigikey for an idea of the breadth of these. It is also possible to buy them in other morphologies, e.g. rods, flexible films..etc

The problem you have is that the mass of the sensor on the leaf will affect the vibrations you record. For this reason, most insect studies utilize non-contact methods (an LDV) for plant vibrations.

For attachment, wax is always a good method, which is common for attaching vibrational sensors. My guess is as much of the disc in contact with the leaf as possible. But, I don't know if a piezo would be sensitive enough in this case to detect your signal.
