Having operated out of Leeds (rotary), the process that is normally followed is outlined below.
When departing from Multiflight at Leeds, you have to 'book out' via telephone with air traffic - the usual list of information is required (type, PIC, destination, etc.) and you nominate a VRP that you would like to use.
You can choose from Keighley (due West of airfield), Dewsbury (due South of airfield), Harrogate (North East of airfield) or Eccup Reservoir (due East of airfield). I believe these are utilised to keep you clear of built up areas and away from the 32/14 approach paths.
On getting your departure clearance, and then when speaking to Approach (125.575), they reconfirm your VRP ("leave the zone via...") along with an altitude restriction (normally not above 2000ft QNH).
On re-joining, it is normal to route via a VRP, but I have been granted more direct approaches when returning to the airfield, especially from the North. I've never overflown Ilkley as this virtually lies on the extended centre line (but I've never really needed to either, so this doesn't mean you can't!).
Essentially, all you can do is ask the Approach controller (or the person taking your booking out information) for a routing and see what answer you get! For an 'international' airport, I've always found the team at Leeds to be friendly and amenable to requests, subject to the work-load at any given time.
Hope you manage a trip up here - there is some stunning aerial scenery around Yorkshire, so I'm sure you (and your father) won't be disappointed!
