This is an assignment that is fraught with peril because there are
so many of these pale lagers around the world and there are so many variables. The idea that you could make something that had the character that your future FIL likes in San Miguel is very unlikely. I think you could make a good, pale lager but the subtle nuances are what will be hard to reproduce. So here is a very straightforward extract recipe for what I would consider a right-down-the-middle light lager.

You might consider using 25% distilled water to lower the bicarb level and to give the beer a smoother character. You may also consider adding 2 or maybe 2.5g of calcium chloride to the water also to create that soft, smooth, rounded character.
I would steep the carapils for 30 minutes at 150°, remove the grain bag and add the DME and rice syrup (which could be found at homebrew supply places but also possibly at a market that carried Asian ingredients) and bring it to a boil Try to do a full-volume boil... the beer will be smoother. Add the bittering hops, just do a 30-minute boil and then add the late hops with five minutes left. I'm inclined to suggest S-189 on the yeast because it's dry (easy to use) and it's got a bit of a European character but it doesn't scream GERMAN or CZECH... it's just a good, all-around dry lager yeast with a nice character. 34/70 is another option although its character is more robust and recognizable. The San Miguel site says it's 5% and this recipe will get you there. The site also says that the beer is a little "smoky" and finishes with a hint of licorice which sounds repulsive and I have no idea if it's true. I believe San Miguel is available at Binnys so maybe see if you can get a sixer and taste it to see what character you pick up and then adjust the recipe accordingly.
I remember being on a board years ago and someone asked about brewing a "light lager". Some people were giving some suggestions, etc. and at some point the guy said, "Hey, I want this beer to taste like Miller Lite. None of this Bud Light crap!" and it was hilarious. To find the subtle differences in all of these pale lagers from around the world you would have to be a master brewer, a chemist, a BJCP judge and very patient. This is a tough assignment Carlos... at the very least you should make a nice, drinkable beer.
