The starting point here is to establish the name of the manor or manors within the Parish you are researching. The Victoria County Histories for Lancashire come in eight volumes. within this set, divided into Hundreds, are to be found historical and geographical detail on every village, township and manor in the County.
Each Manor may have surviving court rolls from a Court Baron or Court Leet, adjacent Rolls should be checked when looking for tenants on a Manor.
Surviving Manorial records, in various forms, should be with the County Record Office and are usually deposited from Private Collections. The Guide to the Lancashire Record Office will point to any deposited records via the index section, look up the name of the area you need. Failing that, the manorial Documents Register, Quality House, Quality Court, Chancery Lane, London, holds a list of all deposited Manorial Documents in CROs.
