If there is no specific place, putting some clothes inside to keep their shape is a good idea.
Putting newspaper to maintain its form is not right because of the possible ink leakage.
It is recommended to remove the straps and put them inside the bag because the metals inside may injure the outer cover, and if they are not removable, putting bags in upright and flat positions are a good way.
Moisture is another issue because molds may come with it.
To remove molds, cleaning them with a soft cloth and putting it in free air is the right way.
Buying an AC and dehumidifier are the other options.
Another issue is color leakage, in particular with colored leathers, patent, and suede, which may be away from the belongings. 
In locations like restaurants and airports, using a bag cover is the right job to avoid the possible stains and dirtiness.
The inner liner is also important because the items like pens, pencils, or cosmetics may damage it.

The leather conditioner is a kind of oil that feeds the leather fibers and prevents them from drying and shrinking and is available in the market in a leather care kit.
In case of conditioner unavailability, how to condition the leather bag at home? The answer is easy: the baby oil is a suitable substitution.
Leather Waterproofing cream is another way.
