As the English you should push out Fyrdmen (or Feudal Sergeants if you don't have VI), UM, Hobilars and archers, and rush the French provinces ASAP. A two front attack is necessary, as this will prevent him consolidating his forces, and you should make for Ile de France early on. In the south you should take Tolouse also. After this you have them badly weakened and should be able to clean up. You need to act fast, attack assault and end it, before the pope starts to complain. Both Navarre and Aragon are good early aquisitions, because the Spanish will backdoor you if you're not careful.
As the French it's a similar strategy except that you should hit the province of Anjou to cut the English continental provinces in half, followed by Aquitaine which now cannot be relieved, making sure that flanders is well garrissoned to prevent any invasion coming from Britain. Normandy is not a priority, if you're careful about it, Brittany can take care of itself for the time being, it is more important to unite the southern provinces. On top of all of this you will have to watch the HRE as well. War with them is a bit of a lottery. For both factions shipping is important, to protect their coastlines.
