The term in question is phrasal verb which is defined as
a phrase which consists of a verb in combination with a preposition or adverb or both, the meaning of which is different from the meaning of its separate parts. Cambridge
When changing the tense of a phrasal verb, only the verb is affected, for the simple reason that adverbs and prepositions do not change with tense, as they are not verbs. It is also crucial to note that phrasal verbs do not come with hyphens. However, a number of them can be hyphenated or compounded to function as adjectives or nouns with related or unrelated meanings.
To use your example, the past tense of mouse over would be moused over, while the present participle would be mousing over. You could also hyphenate to make a noun, as in, "The trackball is so bad that a simple mouse-over to the top-left corner of the screen takes more than twenty seconds."
For reference, here is the definition of mouse over:
mouse (verb)
[with adverbial of direction] use a mouse to move a cursor on a computer screen:
mouse over to the window and click on it NOAD
Some standard phrasal verbs, their tenses and their adjective/noun derivatives:
PHRASAL VERB PAST TENSE PRESENT PARTICIPLE ADJECTIVE/NOUN brush off brushed off brushing off brush-off fall out fell out falling out fallout • falling-out check in checked in checking in check-in cross over crossed over crossing over crossover drop out dropped out dropping out dropout knock down knocked down knocking down knockdown • knock-down see through saw through seeing through see-through shape up shaped up shaping up shape-up stand by stood by standing by standby take away took away taking away takeaway take off took off taking off takeoff • take-off
All this said, there are indeed some standard hyphenated verbs (these belong to the larger group of compound verbs, majority of which do not have a hypen, e.g. backstab, broadside, singsong, overtake, bypass, etc.), but these are not verb-preposition combinations, as you indicated. Rather, they terminate in verbs or are wholly verbal in composition. For these species, the tense change affects the word in its entirety. Examples:
COMPOUND VERB PAST TENSE PRESENT PARTICIPLE (with hyphen) booby-trap booby-trapped booby-trapping flip-flop flip-flopped flip-flopping see-saw see-sawed see-sawing sun-dry sun-dried sun-drying T-bone T-boned T-boning
However, there exists one (and there may be a few more) true hyphenated phrasal verb (verb-preposition) that is treated wholly as a verb: one-up
PHRASAL VERB PAST TENSE PRESENT PARTICIPLE ADJECTIVE/NOUN one-up one-upped one-upping one up [on]
It appears, however, that this verb may be a back-formation from the original noun phrase and, later, adjective, one up.
Yes. The 'to' is part of an implied infinitive, meaning "I will call you back as soon as I am able to call you back". If context is understood (in this case, you have already stated that the intended action is to call back), the preposition is not necessary.

"Intrude" is an intransitive verb so needs the preposition following. I've never seen "intrude" used with any preposition other than "on" but that is a stylistic matter, I think.
"Invade" is transitive and should not take the preposition.
