My typical army configuration and tactics depend on its role either as a defender or an attacker. I spend a good while scouting the terrian andpositon my units before clicking 'begin battle'.
For a defense army I usual have:
4 spears/anti-calv. infantry
2-4 ranged( usually archers)
1-2 heavy infantry
1-2 anti-armor infantry
2-6 calvery ( including usually the General)
I find a nice hill near the edge of the map and position infantry in a semi circle with rows of archers behind them. I set the spearmen to hold position and hold formation and turn off the archers fire at will a group all of them together then set them to hold positon as well. My general stands just behind the last row of archers with infantry mix at his sides. Finally I cover the flanks with a mix of light and heavy calvary on both sides.
I send out some light calvary to harrass the enemy while they march to my position with the hope of routing thier archers and luring thier calvery out to take a flank attack from some more of my calvary. The AI will almost always pursue my general so I sometimes take the general out as bait for this manuever. I will allow the enemy's spearmen to pursue my calvery into an ambush from my ranged attackers and heavy infantry as well. Luring calvery into woods with hidden spears lying in wait is a nice tactic as well.
If I haven't routed the enemy by the time they line up in front of my position, I continue to harrass ranged and non-spear infantry units with my calvary while concentrating ranged attacks on the advancing spear ranks. I send out my heavy infantry and militia to meet any infantry they send up the hill towards me and try to take out their spearmen from the flanks in order to give my calvary more room to harrass thier ranged units. If they charge with calvary I let my spear ranks take the blow and attack the calvery flanks with my own calvary and a reserve of spear I keep back just for the occassion.
Once they are running away ( and they always do!

), I unleash all my fast units to persue and take the easy pickings. If they regroup or call for reinforcements I will reform my postions, withdraw depleted units and pull fresh units from my reserves if I have any( I usually do). Then I rinses and repeat as nesseccary!
I'll post my offensive army/tactics later.
