VHDL is an industry-standard language for modeling and synthesizing digital hardware, particularly for programmerable logic or Application Specific Integrated Circuits. So, for example, because most of the default offsets are defined in terms of +, -, and 0, if you like the general indentation style, but you use 2 spaces instead of 4 spaces per level, you can probably achieve your style just by changing vhdl-basic-offset. To start the process, select "New Source" from the menu items under "Project". Behavioral Modeling allows a system's functionality to be described using common programming language forms. If you must use VHDL 2002, then there is an application note on the OSVVM website explaining how to make the code compatible with VHDL 2002.
