"Beating Unusual openings" by Richard Palliser has several chapters on 1.c4 -
For practical play you could review the games of MotownDave one of the 2000+ players here on RHP.
Here's a flavour from the Richard Pallisers book:
Chapter 1
White Fianchettoes and plays Nf3
1.c4...c5, 2.Nc3...Nc6, 3. g3...g6, 4. Bg2...Bg7, 5. Nf3 and then: A: 5...e5, B:...d6!?, C:...a6!?
Chapter 2
White Fianchettoes without Nf3
1.c4...c5, 2. Nc3...Nc6, 3.g3...g6, 4. Bg2...Bg7 and then : A: 5.a3, B: 5.b3, C: 5.e4
"These three systems can lead to some strategically rich positionjs, and that has helped each of them to gain a dedicated following. Ahain the Botvinnik set up is a good way for bloack to respond although he must be alert to move order nuances especially in line A.
Chapter 3
The Three Knights Variation
1.c4...c5, 2.Nf3...Nc6, 3. Nc3 A: 3...e5, B: 3...Nd4!?
Chapter 4
White Plays and Early d4
1.c4...c5, 2. Nf3...Nc6, 3. d4...cxd4, 4. Nxd4...Qb6!, 5.Nb3...e6, 6.Nc3...Nf6 and then
A:7.e4, B: 7a3, C: 7g3

not the most dynamic, not the most interesting, it is the most balanced and symmetrical
