A few hints
Spoiler Alert, click show to read: 
The Citizen cavalry and King's Elites seem to me to be crucial to dealing any real damage or breaking phalanxes, if these units get exhausted quickly or suffer heavy casualties, the job will be a lot harder.
Take out those Syrian archers quickly or they'll just mow your infantry down.
Don't fight the phalangites, draw them apart and slowly surround them.
