Transciever is a must and all the transcievers are surfice mount type. Most are 8 pin SOIC package. Cracking an old pc motherboard will give you a good starting point for creating custom board with surfice mount components.

If you plan to add support for CAN bus vehicles, there is an available break board with tja1050 transciever ready to be linked with arduino or other types of interface.
