I`m not sure what you`re looking for , so I`m just taking a shot here.
I started with real wood textures, then :
1) New Layer. Fill w/ blue.
2) Add noise. how much will be determined by file dementions and resolution. Play with it.
3) Motiin blur, 90 degrees. Again play with the amount. Set to Color Mode. 70-80 %
4) Duplicate color layer, Go Filter>>Stylize>>Emboss, Adjust Curves to add contrast. Set to Lighten Mode, 40-50 %
5) Filter>>Distort>>Shear to make the brush strokes stand out a bit more.
