there aren't specific lager or ale malts - lager v ale is dependent on the yeast strain
you can use any IPA recipe but try to chose a grain bill that is light on crystal malts as you want a nice crisp finish - if you are using extract use a light version and avoid adding much if any extra crystal. consider replacing some of the extract with a simple sugar as well
you want to increase your late hops to compensate for the extra time lagering and possibly fermenting in which the hop profile will fade
the AG version I did used a lb of hops total incl a couple dry hop additions. i did a 4oz 30min hop stand as well once the wort cooled to around 160°
a pilsner strain may be a good choice, you want something that won't emphasize the malt too much
cool a few/several degrees below you target ferm temp and pitch a huge starter
It didn't really jump out to me as a lager instead of an ale, although I used some yeast from a batch of oktoberfest (wyeast 2308 I believe) which is known to emphasize the malt. it was a fun experiment but I don't think the extending aging and loss of some hop profile was worth using lager yeast instead of ale yeast.
