Sorry to say but the Byzantines abondoned those tactics long ago during the fall of the the WRE and the dark ages. Then tactics changed some more.

My research on them is most generaly this:

-double line inf.

-left cav forces defensive,

-right cav forces are flanker (alexander tactics)

-if outnumbered do no lenghten lines, attack flanks (I tried, its -hard- but works)

-they used pikemen but spear units can be used to represent this.

-HA are almost exclusively mercenaries.

-HA ahead of army to skirmish

-archers behind inf.

-inf. had a part in the army, but in the mid-east its the CAV that does the talking so cav is like the most important part of the army.

-general never engages, so they wont die (I learned the hard way)

-most important, they were never warlike! at this period they avoided battle as much as possible, and used bibes and diplomated much.
