IIRC from my microbiology course, the major difference between bacteriophages and animal viruses was that almost all bacteriophages enter the cell through the injection of naked DNA. Animal viruses on the other hand almost always enter via endocytosis, receptor-mediated endocytosis (i.e., clathrin-mediated) or fusion of the plasma membrane.
Another difference is that most bacteriophages exit via lysis. Animal viruses on the other hand have two modes of exit: budding without lysis (for enveloped viruses) and rupture of the plasma membrane (for non-enveloped viruses).
With respect to the lytic cycle/lysogenic cycle. I think the main difference is that all bacteriophages must undergo these cycles. In animal viruses however, integration into host genome is only one mechanism of animal viral propagation. There are other methods of viral propagation in animal viruses.
