I'm looking to design a bandpass filter using OP-AMPs that is unity gain and will approximate the following filter curve.
I've got +/- 12V to work with and will either use a DPDT relay or switch to bypass the filter when it is not needed.

Have a play with some filter design tools from TI and Analog Devices.
TI asks you to create an account to see the full design whereas Analog Devices provides the complete design.
The Analog Devices version will also provide a LTspice circuit of the filter.
I played around with the Analog Devices Filter Wizard:
These values will get close to the filter response, you may need to vary the values to get the exact response you require.
